I have a bunch of SQL scripts (with shell script wrappers) to unload data like so
EXPORT TO /tmp/out.csv OF DEL MODIFIED BY NOCHARDEL COLDEL, DATESISO
MESSAGES /tmp/out.msg SELECT WIDGETID
...
I want to add an error handler to the script the way Oracle does it:
WHENEVER SQLERROR EXIT FAILURE;
SPOOL /tmp/out.csv;
SELECT WIDGETID...
SPOOL OFF;
According to DB2's documentation, this can be done in stored procedures, C, Perl, REXX, and nothing else...
How can this be done in SQL scripts?
I am running DB2/LINUXX8664 9.7.2.
you could use the DB2 command line command processor and get its return code. http://publib.boulder.ibm.com/infocenter/db2luw/v9r5/topic/com.ibm.db2.luw.admin.cmd.doc/doc/r0010411.html
or you could use the SYSPROC.ADMIN_CMD procedure and use its return codes. http://publib.boulder.ibm.com/infocenter/db2luw/v9r5/topic/com.ibm.db2.luw.sql.rtn.doc/doc/r0023573.html
you could put the stored proc calls in a script file and run something like db2 -tvf runexport.txt or put the db2 commands in a linux script file and use linux scripting foo to handle the db2 return codes.

http://pgtap.org/integration.html#perl mentions how to run the tests, but I cannot find an example of a Perl test case.
Do I have to get a DBI connection manually, run my commands on it, and check the results?
Does it even make sense to use Perl vs SQL code?
Am I missing something?
pgTap is for parsing SQL output - output from running an SQL script via psql from the command line. An SQL script that contains pgTap SQL calls mixed in with the SQL statements that you wish to test.
As such, DBI doesn't enter into it.
I am facing a problem in DB2. In my Oracle environment it was very easy for me to include multiple scripts in one master script, which were executed sequentially. e.g.:
Master.sql:
connect ....
#script1.sql
#script2.sql
Now I have to build up same logic in DB2 LUW. Is there a simple way to include multiple scripts in one master script? I would like to have one single db2 call from shell, which executes the master script and within all subscripts.

There is notrhing to stop you from creating a single file with multiple sql batches. In the Windows world, it would look like this:
Note: First you initialize the db2 command prompt.
db2cmd -c -w -i %1.bat
With as many of these as you want in the .bat file:
db2 -txf c:\Example\db2html.sql
In Linux, the db2clp is included in the shell once you load the db2profile ('. /home/db2inst1/sqllib/db2profile). In windows, you need to call db2cmd in order to use db2clp.
With a interactive db2clp, you cannot call db2 scripts via #scriptX, however, you can call them from the shell like
db2 -tvf script
However, if you use the CLP*Plus you can do almost everything you do in SQL*Plus. For more information: https://www.ibm.com/developerworks/community/blogs/IMSupport/entry/tech_tip_db2_s_new_clp_plus_utility?lang=en
I have a script in a file (mysqlscript.sql) that is basically a bunch of inserts/updates/deletes separated by GO statements
insert into ....
GO
update .....
GO
How do I run this script?
You can try to use $system.SQL.ImportDir()
And of course, you can read your file and execute each sql-query in your programm.
The tool Caché Monitor use GO as statement separator and connects to InterSystems Caché. With this tool you can execute your script.
What JCL EXEC and DD statements would be required to run a COBOL program that
Reads and inserts to a DB2 table
has PCLog for good run and abends
I don't need the actual code, but I'm looking to know what's required in terms of exec statements. If possible, the DD's for the execs would be handy too.
EXEC PGM=IKJEFT01
This utilitit allows you to
Execute DB2 programs in COBOL
BIND to DB2
Unload DB2 data
what is the procedure in SQL server to not execute anything(T SQL commands) but outputs the commands it would execute
There isn't one unless you are using dynamic SQL where you'd use PRINT
You can see a stored proc definition but this won't show you any actual parameter values etc
Are you thinking of SET SHOWPLAN_TEXT ON?
